`To' azz'whtmetag 0mm j l Be it known that I', ,CLEMENT Boorri, .a`

` citizen ofthe United States, re'siding at llion,

i in ty connection between the t New York,"have invented certain new and useful Im rove'ments in Type-Vlriters,.` of. whichtheiollowing isa clear, full, and exact description. My inve 'tion relates to anv improvement writers, and my vobject is to provide a and' eiiicient' construction of'. pivot pe bar and. its hanger, so that .theplay-o said connection may be readily adjustedas desired.

My invention will be vset forth in the claims.`

In the drawings, Figure 1 is asectional view of that much oi -a typewriter aswill readily illustrate. lthe applicationof this insimp e vention; Figi''is a sectioiialview on line 3-1-3 the pivot connection. 5'5

fork, and' I have shown the type b of Fig-Zlig. 2 is a side -elevation of the an underneath plan of Fig. 3; Fig. 5 is a perspective vview of the adjusting bolt;Fi 6 is a perspective view of the ti'ghtening tool; Fig. 7 is a view similar to Fi 1 showing my invention applied to a visi le writing ina-- chine; Fig. 8 is a side elevation of my preferred form of type bar and adjusting means; Fig. 9 is a transverse section on line 9`9 of Fig. 8; and Fig. 10 is a perspective view of a detail. 4

In the above embodiment illustrated in Fig. 1 to 7 inclusive, 1 isa hanger in which the t e bar 2 ispivoted, said hanger 4being provi ed with means for slightly adjusting the position of the same in order to siightl vai-K the position Y, at which the 'type wil stri e the paper, such .means consisting (in the present embodiment) of a screw passing through a suitable slotin the er. One of sai parts is made inthe form o a spring ar as 4 formed at one endinto 'such-'fork, the legs 4, 5, of which straddle and are dpivoted upon a stationary pivot-bar 6 carrie by the hanger. In lorder to ad'ust the play of the pivot connection I pre erably provide a cam portion 8 `whichis adapted to contact with incline faces 9 and 10 on the legs of the fork,

and a suitable threaded device such as a nut and bolt 11 to draw saidcam portion 'a ainst the incline faces on lsaid. legs in or er to draw said legs together so as tol tighten Vup y It willbe obSerVedthat, in the embodi? ment illustrated in the' drawing, thel nut or l as tliis attains many advantages. observed that if ipis desired to slightl lbolt -11causesthe cam orton to move longitudinally of the' type lorder tovmakc the reqiiired adpistinent. 12 represents one of the cys of t ie typewriter, and 13the platen.

ar and is in aI position such that it may be' readily gotten at in I prefer `that fthe adjustable mechanism shall be allcariied upon the type bar itself, It will be adjust theffposition at 'whichthe type sli'a 'strike the paper, it may be done by s ightly shifting .the position of the hanger without interfering Vwith .or changing the adjustment of the 'pivot connection.

ther advantages will be apparent to those skilled in the art.

the nut 11..'4 `Itis provided with a'central Arecess fand projecting edges straddling the recess .adapted to engage a slot inthe nut. pivot and of my improved typebar; Fig; 4 is In the referred embodiment of my invention as il ustrated in Figs. 7l to 10 inclusive,

514 represents the platen ofavisible writing typewriter, 19 a key lever, 25 a link connect- The ,tool 14sliown in Fig.f6 maybe used to adjust ingthe lever 19 with the .arin 26 of the type bar 18. 15 represents the standard to which is secured the hangers 16.

The' t e barV 18 is preferably of one piece having a jifurcated butt end straddling the hanger 16 and rlpivoted on a pivot bar 21 fixed thereto. he butt end is drilled to per- 'mit the passage of an ordinary screw 17 and straddling legs 27 are provided as shown with bevels 20, 20 and 22, 23.- The cam or wedge 24 is located between these bevels and is threaded to receive the screw 17;

' Upon turning the screw to draw the -wedge forward, lthe legs 27 will be s ueezed'together to take up lost motion, Wh e upon moving the screw and wedge o positely, the legs wil spread on account of t e spring of the metal.v

While in thel foregoing I have described and illustrated the referred form of my invention, it will be ol vious that the construction illustrated may be varied without departing from the s irit of my linvention as claimed, and thereibre do not liinit myself to the embodimentshown in the drawings.

What' I claim'is: s

1.'In atypewriter in combination, a hanger, a type bar having at one end a fork pivoted to said hanger, andmeans carried y said vtype bar acting lengthwise thereof for adjusting the legs of said fork-'to adjust the play of said pivot.

2. I n a typewriter in combination, a

, lio

winger provided with a iXed pivot-bar, a type bar having at one end a fork straddling and. pivoted to said pivot-bar, und means carried by said type bar and acting lengt-l1- wise tlieieoi for adjusting the legs of said fork` to adjust the play of said pivot 3. In a typewriter in combination, a hanger7 a type bar having at one end. a i'ork pivoted to said hanger, and means carried by said type bar for adjustingl the legs of said fork to adjust the play of said pivot, said means comprising a movable cam adapted to contact with the legs of said fork to vary the distance between the same and an adjustable threaded device to move said cam at will.

. 4. In a typewriter in combination, (a hanger provided with means for slightly adjusting the u ing a pivot-bar, a type bar formed at one end into a spring fork straddling and pivoted on said pivot-bar, a cam portion carried by and movable longitudinallyof said typebar and acting against the legs ot said fork to draw them together, and a threaded device also carried by said type bar to move said .cam portion to vary tile play of said ivot.

5. In a typewriter in com ination, a hanger (provided with means for slightly adjusting the positionedc the same) and type bar, one of said parts having a spring fork) the legs oi which are pivoted to saidV other part, said fork being provided with a cam portion adapted to move longitudinali' of said fork and contact with the legs of the same to vary the distance between said legs to adjust the play of said pivot connection,

j and threaded. means adapted to move said cam ortion at will.

6. LIn a typewriter machine in eo1nbinaj tion7 a hanger provided with a pivot bar, a 40 j type bar bifurcated at one end and mounted i upon said pivot bar, the arms of said bitur` cated portion being slotted in ojzpositelv inclined directions, the wells of .said slols l forming oppostely inclined lvevclcd faces. a

movable cani located adjacent thereto', linvving two oppositely inclined beveled faces to cooperate with the beveled faces of the slotted arm portions and means to move said cam. Y

7. In a typewriter machine 1n combinal tlon, a solid one piece hanger )rovided with I A j a pivot bar7 a one piece type )ar bifurcated position of the same and carrvat one end to embrace the hanger and pro- -vided with bearings tor said pivot bar, the

arms of said bifnrcated portion being slotted in ofppositely-inclined directions the walls of said slots forming oppositely-inelned beveled faces, a movable cam located adjacent thereto laving two cpositel'*-inclil1ed beveled faces @0 to cooperate with t 1e beveled faces of the slotted arm portions, said cam adapted when moved to compress the bearings of the bifurcated arm portions upon the pivot bar, and a screw-threaded bolt engaging with said cam to operate the same.
